Blizzard has confirmed that there will be no support for LAN gaming in the upcoming release of StarCraft 2. All multiplayer games must be done through Battle.Net
Blizzard today confirmed for GameSpot that LAN functionality will be absent from Starcraft II's multiplayer component, as both a piracy prevention mechanism and a quality-assurance initiative.
"We don't currently plan to support LAN play with Starcraft II, as we are building Battle.net to be the ideal destination for multiplayer gaming with Starcraft II and future Blizzard Entertainment games," a Blizzard representative said in a statement. "While this was a difficult decision for us, we felt that moving away from LAN play and directing players to our upgraded Battle.net service was the best option to ensure a quality multiplayer experience with Starcraft II and safeguard against piracy."
